Rewrite each of the following in radical form:

radical form: n√x^m

rational exponent form: x^m/n

we can just move around each digit to convert the numbers from rational exponent form to radical form.

1. radical form: 2√5

because 5 is being raised to the first power, we don't need to show it.

2. radical form: 3√5

because 5 is once again being raised to the first power, it's redundant to show it.

3. radical form: 2√5^3

50-38=12

step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
